To all whom it may concern:

Be it known that 1, WILLIAM R. JEAVONS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Tanks and Gages Therefor, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

Thisinvention relates to tanks and gages therefor.

While some of the features of construction are of universal application, the invention disclosed herein is particularly well adapted for tanks associated with and forming part of the construction of oil stoves and serving to supply oil to the burners I thereof.

- The general objects of the invention are to produce a tank and gage of this character which are extremely simple in construction, inexpensive ofproduction, but, nevertheless, of great eliiciency in operation.

A further object of the invention is to combine a gage with a tank of this character in such a manner that the gage may be firmly and-unyieldingly supported and be protected against breakage.

Still further objects of the invention will be set forth hereinafter in connection with the detailed description of the particular embodiment disclosed in the drawings hereof, wherein Figure 1 represents an end elevation of a tank having my gage applied thereto; Fig. 2 a central vertical sectional view through a tank and gage such as shown in Fig. 1, illustrating the manner in which the gage is supported within the end of the tank; and Fig. 3 a sectional detail of one'of the caps or heads by which an end of the tank is closed,

showing the manner in which the gage may be assembled within such head or cap.

Describing by reference characters the various parts illustrated herein, 1 denotes the cylindrical wall of a tank for an oil stove, this shape (cylindrical) being that most ordinarily employed for the tanks of such stoves. One end of the tank is closed by a cap or end piece 2, of ordinary construction, such cap or end piece being seamed onto theadjacent end of the tank wall 1, as by means of the curled edge 3 inclosing the outwardly flared end 4: of the Wall 1, the parts being soldered together. The cap for the oppos1te end of the tank,

' however, is especially prepared in order to 1. The wall 5 projectsinwardly from the cylindrical wall 6, the latter wall extending substantially parallel with the wall 1 and forming with such wall an annular space 7. At its outer end, the cap comprising the walls 5 and 6 is flared outwardly, as shown at 8, and is seamed onto the adjacent end of the tank wall 1 in the same manner as the cap 2 issecured to the opposite end of the tank wall, the curled edge 9 on the outer end of the cap inclosing an outwardly projecting flange 10 formed on the end of the wall 1. By this construction, it will be apparent that the cap which is opposite the cap 2 has its major portion, and particularly the wall 5 thereof, inset or recessed with reference to the end of the tank wall 1. This results in providing a space within and protected by the overhanging end of the tank wall 1, and within this space the gage is located.

The gage proper comprises a tube 11 of glass, or similar transparent material, the ends of which are supported within sockets 12 and 13. These sockets areexactly identical except'that the socket 12 has an elongated reduced neck 14 while the socket 13 has a neck 15 which is relatively short as compared with the neck 14, although it is also reduced in diameter. Each socket is provided with a flange 16 against which the adjacent end of the tube 11 is adapted to abut. It will be noted that each socket is of considerablygreater diameter than the external diameter of the tube 11, thereby providing an annular space surrounding each endof the tube 11, this annular space being adapted to receive a packing. For this packing, I prefer to employ lead, which is inserted in place and 18 then tamped or pressed. into the space between the socket and the adjacent wall of the tubell, thereby forming a tight and non-leaking joint, as

indicated at 1 Reference has been madeheretofore to the jfact that the neck 14 is longer than the neck 15. The purpose of making these necks of unequal lengt will be apparent from an inspection of Fig. 3, wherein the gage is shown as being assembled within the cap 5,

6, 8. The neck 14 will be of such length as will enable the bottom of the neck 15 to be slipped into place within the flange 6 and gage end of its sockets 12 and 13 is such that,-

when assembled, the gage is entirely within the inset or depressed end of the tank and is completely protected by the projecting end of the tank. It will be noted further that the ends of the gage are in free and open communication with the interior of the tank by means of the annular passageway 7 which is provided between the flange 6 and the wall 1.

In section. in Fig. 2 of the drawing, there is shown the float which it is preferred to employ. This float comprises two cylindrical-sheet-metal members, preferably of aluminum, each having an open end and a closed end and arranged to telescope one within the other. 18 denotes the cylindrical wall of one of these members and 19 the closed end of the same. This member is shown as telescoping within the other member, the latter member comprising a cylin-' drical wall 20 and a closed end 21. When assembled, these two members forin in effect a capsule, the walls 18 and 20 of which fit sufliciently close to prevent the passage of liquid therebetween to the air space within the float.

It will be observed that the side wall of the outer member extends the full length of the inner member, so that the-end of said wall extends as far as the closed end of the inner member. With this arrangement of parts, there can be no passage of liquid through the space between the walls of the two members. This result might occur through the cooling and consequent contraction of the air within the float, which contraction would tend to suck in the liquid. If the annular space between the walls 18 and 20 were short, liquid might work through this space and sink the float.

From the foregoing description, it is believed that the operatioi'i of the device will be clear. Owing to the free communication of the ends of the gage with the tank, through the necks 15 and 14 and the annular space 7 the liquid will stand at the same level in the tank and in the gage. The float 18-21 will rise and fall with the liquid in the gage and will indicate the height of the liquid in the tank. The gage itself is particularly simple of construction, but is of marked ethciency.v The manner of connecting the gage with the tank insures adequate protection of the gage and a permanent,

rigid connection with the tank. Furthermore, the manner of constructing the gage and of assembling it in connection with the tank prevents any leakage of liquid either around the necks 1% and 15 or between the flanges 12 and 13 and the ends of the tube 11.

Having thus described my invention, what I claim is:

1. The combination, with the side wall of a tank, of an end having opposed inwardly projecting portions spaced from the side wall, and a gage entirely within the in wardly projecting portionsof the end and communicating with, the tank through such portions.

2.
